In order to make the objects, technical solutions and advantages of thisapplication clearer, the technical solutions of embodiments of thisapplication will be clearly and comprehensively described in thefollowing with reference to the embodiments of this application. It isapparent that the described embodiments are a part of the embodiments ofthis application, rather than all of the embodiments. All otherembodiments obtained by a person skilled in the art based on theembodiments of this application without creative efforts shall fallwithin the protection scope of this application. The followingembodiments and features in the embodiments may be mutually combined ifno conflict occurs.

FIG. 1 is a schematic structural diagram a first embodiment of avaporizer according to this application.

To resolve the technical problem of severe liquid leakage of thevaporizer and the electronic vaporization device in the related art, anembodiment of this application provides a vaporizer 1. The vaporizer 1includes a first air inlet 11 and a first air outlet 12. The vaporizer 1further includes a first airflow channel 13, where the first airflowchannel 13 is in communication with the first air inlet and the firstair outlet 12, and a vaporization assembly 14 is arranged in the firstairflow channel 13. The vaporizer 1 further includes a second airflowchannel 151, where two ends of the second airflow channel 151 separatelyintersect with the first airflow channel 13 to form a first intersection1511 and a second intersection 1512, where the first intersection 1511is located between the first air outlet 12 and the vaporization assembly14, and the second intersection 1512 is located between the first airinlet 11 and the vaporization assembly 14.

The vaporizer 1 further includes a capillary liquid absorbing structure152, and the capillary liquid absorbing structure 152 is connected tothe second airflow channel 151. When an inhaling action occurs at thefirst air outlet 12, accumulated liquid in the first airflow channel 13that is close to the second intersection 1512 enters the second airflowchannel 151 through the second intersection 1512 and is absorbed by thecapillary liquid absorbing structure 152. Detailed descriptions areprovided below.

In an embodiment, the vaporizer 1 is a component that is configured tovaporize an aerosol substrate in an electronic vaporization device.

The electronic vaporization device to which the vaporizer 1 of thisembodiment is applied may be an e-cigarette or the like, and thevaporizer 1 is configured to vaporize e-liquid (that is, an aerosolsubstrate) for a user to inhale. Certainly, in other embodiments of thisapplication, the electronic vaporization device to which the vaporizer 1of this embodiment is applied is not limited to a product form of thee-cigarette. For example, the vaporizer 1 of the electronic vaporizationdevice may be further configured to vaporize liquid medicine, or thelike. The vaporized liquid medicine is provided for the user to inhale,so as to assist in the user's medicine treatment. The followingdescription is given by using an example in which a product form of theelectronic vaporization device to which the vaporizer 1 of thisembodiment is applied is the e-cigarette, which is only for descriptionneeds and is not intended to constitute a limitation.

Specifically, the vaporizer 1 includes a first air inlet 11, a first airoutlet 12, and a first airflow channel 13 that is in communication withthe first air inlet 11 and the first air outlet 12. When the userinhales, that is, an inhaling action occurs at the first air outlet,external air enters the first airflow channel 13 from the first airinlet 11 and flows toward the first air outlet 12 along the firstairflow channel 13.

Further, a vaporization assembly 14 is arranged in the first airflowchannel 13. The vaporization assembly 14 is a component that isconfigured to vaporize an aerosol substrate in the vaporizer 1. When theuser inhales, the air entering the first airflow channel 13 from thefirst air inlet 11 carries the aerosol substrate vaporized by thevaporization assembly 14 and flows toward the first air outlet 12, andis outputted from the first air outlet 12 for the user to inhale.

Optionally, the vaporization assembly 14 is preferably a porous heatingbody, which absorbs the aerosol substrate by a capillary force andgenerates heat to vaporize the aerosol substrate. Preferably, thevaporization assembly 14 may be a porous ceramic heating body, or thelike, and a heating film may be further arranged at the bottom of thevaporization assembly. Certainly, in other embodiments of thisapplication, the vaporization assembly 14 may alternatively be suchdesigned that fiber cotton and a heating wire are matched, which is notlimited herein.

The vaporizer 1 further includes the second airflow channel 151. Thesecond airflow channel 151 is spaced apart from the first airflowchannel 13, and two ends of the second airflow channel 151 separatelyintersect with the first airflow channel 13 to form a first intersection1511 and a second intersection 1512.

The vaporizer 1 further includes a capillary liquid absorbing structure152, and the capillary liquid absorbing structure 152 is connected tothe second airflow channel 151 and is configured to absorb accumulatedliquid entering the second airflow channel 151.

Because the vaporization assembly 14 is designed in the first airflowchannel 13, the aerosol substrate absorbed by the vaporization assembly14 inevitably remains in the first airflow channel 13. In addition,because a temperature of the vaporized aerosol substrate is relativelyhigh, and a temperature of an inner wall of the first airflow channel 13is relatively low, the vaporized aerosol substrate undergoes a sharptemperature drop and condenses when contacting the inner wall of thefirst airflow channel 13, and the condensed aerosol substrate remains inthe first airflow channel 13. Therefore, the foregoing factors cause theaerosol substrate to remain in the first airflow channel 13, that is, toform accumulated liquid. However, when too much accumulated liquidremains in the first airflow channel 13, the accumulated liquidinevitably leaks to the outside of the vaporizer 1.

In view of this, in this embodiment, the second airflow channel 151 isdesigned. The first intersection 1511 is located between the first airoutlet 12 and the vaporization assembly 14, and the second intersection1512 is located between the first air inlet 11 and the vaporizationassembly 14. That is, the first intersection 1511 is close to the firstair outlet 12 relative to the second intersection 1512. In this way,when an inhaling action occurs at the first air outlet 12, an air flowfrom the first air inlet 11 to the first air outlet 12 is generated inthe first airflow channel 13, air pressure of the first airflow channel13 at the first intersection 1511 is less than air pressure of thesecond airflow channel 151 at the first intersection 1511, and airpressure of the first airflow channel 13 at the second intersection 1512is greater than air pressure of the second airflow channel 151 at thesecond intersection 1512. Therefore, a pressure difference between thefirst airflow channel 13 and the second airflow channel 151 at thesecond intersection 1512 drives accumulated liquid in the first airflowchannel 13 that is close to the second intersection 1512 to enter thesecond airflow channel 151 through the second intersection 1512 and beabsorbed by the capillary liquid absorbing structure 152 to reduce theaccumulated liquid in the first airflow channel 13. Therefore,alleviation of the liquid leakage of the vaporizer 1 is facilitated andthe user experience is improved.

It should be noted that, when an inhaling action occurs at the first airoutlet 12, the external air enters the first airflow channel 13 from thefirst air inlet 11. The air flow from the first air inlet 11 to thefirst air outlet 12 is generated in the first airflow channel 13. Inaddition, part of the air entering the first airflow channel 13 from thefirst air inlet 11 flows into the second airflow channel 151 from thesecond intersection 1512, and the air in the second airflow channel 151converges from the first intersection 1511 to the first airflow channel13, to form a complete airflow path, as shown by dashed arrows in FIG. 1. That is, only when an inhaling action occurs at the first air outlet12, a pressure difference is generated between the first airflow channel13 and the second airflow channel 151 at the second intersection 1512.Therefore, the accumulated liquid in the first airflow channel 13 isdriven to flow into the second airflow channel 151 through the secondintersection 1512. When an inhaling action does not occur at the firstair outlet 12, that is, when the user does not inhale, air pressure inthe first airflow channel 13 is about one standard atmospheric pressure,namely, about 101.325 kPa, and an air pressure difference between thefirst airflow channel and the second airflow channel 151 is not obvious.In this case, the second airflow channel 151 absorbs a relativelylimited amount of accumulated liquid in the first airflow channel 13.

In addition, in this embodiment, the second airflow channel 151 isconfigured to cooperate with the capillary liquid absorbing structure152 to absorb the accumulated liquid in the first airflow channel 13,and is not a cavity used for storing the aerosol substrate of thevaporizer 1. For example, in the electronic vaporization device in theproduct form of an e-cigarette, an e-liquid cavity is usually designedin the vaporizer 1 to store e-liquid (that is, the aerosol substrate).

The first air inlet 11 and the first air outlet 12 of the vaporizer 1 inthis embodiment may be spaced apart in a straight-line direction, thatis, the vaporizer 1 in this embodiment is designed in a straight liquidform. Certainly, in other embodiments of this application, the vaporizer1 may alternatively be designed in other forms than the straight liquidform, which is not limited herein.

In an embodiment, the second airflow channel 151 is connected to thecapillary liquid absorbing structure 152, and is configured to absorbthe accumulated liquid entering the second airflow channel 151 from thesecond intersection 1512.

Further, the capillary liquid absorbing structure 152 includes aplurality of capillary grooves 1521, and the capillary grooves 1521 canabsorb and store the accumulated liquid entering the second airflowchannel 151 from the second intersection 1512 by the capillary force, asshown in FIG. 1 . In addition, the plurality of capillary grooves 1521are spaced apart sequentially in an extension direction of the secondairflow channel 151 and are in communication with the second airflowchannel 151, where the capillary grooves 1521 that are relatively closeto the second intersection 1512 are preferentially configured to absorband store accumulated liquid entering the second airflow channel 151. Aspecific structural design and implementation of the capillary groove1521 are described below.

Still referring to FIG. 1 , in an embodiment, the first airflow channel13 includes an air outlet channel 131 and a vaporization cavity 132,where a vaporization assembly 14 is arranged in the vaporization cavity132. The air outlet channel 131 is in communication with thevaporization cavity 132 and the first air outlet 12, and thevaporization cavity 132 is further in communication with the first airinlet 11. That is, the first air outlet 12, the air outlet channel 131,the vaporization cavity 132, and the first air inlet 11 are sequentiallyin communication with each other.

A cross-sectional area of the air outlet channel 131 is less than across-sectional area of the vaporization cavity 132. When an air flowfrom the first air inlet 11 to the first air outlet 12 is generated inthe first airflow channel 13, a cross-sectional area of the air outletchannel 131 is relatively small, a flow velocity of the air flow in theair outlet channel 131 is relatively high, and correspondingly the airpressure is relatively low. Increase in a pressure difference betweenthe air outlet channel 131 and the vaporization cavity 132 isfacilitated, to make it convenient for the vaporized aerosol substrateto be better provided for the user to inhale.

Cross-sections of both the air outlet channel 131 and the vaporizationcavity 132 are perpendicular to their respective extension directions.In addition, an extension direction of the air outlet channel 131 isdefined as a direction extending from the vaporization cavity 132 to thefirst air outlet 12, and an extension direction of the vaporizationcavity 132 is defined as a direction extending from the first air inlet11 to the air outlet channel 131. For example, in the vaporizer 1 in thestraight liquid form shown in FIG. 1 , the extension directions of theair outlet channel 131 and the vaporization cavity 132 are both thedirection from the first air inlet 11 to the first air outlet 12.

In addition, the first intersection 1511 is arranged in the air outletchannel 131, and the second intersection 1512 is arranged in thevaporization cavity 132. In this way, when the air flow from the firstair inlet 11 to the first air outlet 12 is generated in the firstairflow channel 13, the air pressure of the air outlet channel 131 isless than the air pressure of the second airflow channel 151, and theair in the second airflow channel 151 flows into the air outlet channel131 through the first intersection 1511; and the air pressure of thevaporization cavity 132 is greater than the air pressure of the secondairflow channel 151, and the air in the vaporization cavity 132 flowsinto the second airflow channel 151 through the second intersection1512, to form the foregoing complete airflow path.

Certainly, in other embodiments of this application, when an inhalingaction occurs at the first air outlet 12, the air flow from the firstair inlet 11 to the first air outlet 12 is generated in the firstairflow channel 13. Therefore, in the direction from the first air inlet11 to the first air outlet 12, the air pressure in the first airflowchannel 13 is represented as gradually decreasing. In view of this, thefirst intersection 1511 and the second intersection 1512 mayalternatively be both arranged in the air outlet channel 131 or may beboth arranged in the vaporization cavity 132. Provided that it isensured that the first intersection 1511 is close to the first airoutlet 12 relative to the second intersection 1512, a design foralleviating the liquid leakage of the vaporizer 1 in this embodiment ofthis application may be implemented. In an exemplary embodiment, thesecond intersection 1512 is located at the bottom of the vaporizationcavity 132, so that the accumulated liquid at the bottom of thevaporization cavity 132 may be absorbed by the capillary liquidabsorbing structure 152 along the second airflow channel 151 duringinhaling.

Specifically, when the air flow from the first air inlet 11 to the firstair outlet 12 is generated in the first airflow channel 13, air pressurein the vaporization cavity 132 is P1, air pressure in the air outletchannel 131 is P2, and air pressure in the second airflow channel 151 isP3, where P1 is greater than P3, and P3 is greater than P2.

The air pressure of the vaporization cavity 132 is greater than the airpressure of the second airflow channel 151. A pressure differencebetween the vaporization cavity 132 and the second airflow channel 151at the second intersection 1512 drives the accumulated liquid in thevaporization cavity 132 that is close to the second intersection 1512 toenter the second airflow channel 151 through the second intersection1512 and be absorbed by the capillary liquid absorbing structure 152.

In an embodiment, a volume of accommodation space in the second airflowchannel 151 and the capillary liquid absorbing structure 152 is lessthan a volume of accommodation space in the vaporization cavity 132.Accommodation space is defined as space used by a cavity to store theair and the aerosol substrate. A volume of the accommodation space inthe second airflow channel 151 and the capillary liquid absorbingstructure 152 is relatively small. When the air flow from the first airinlet 11 to the first air outlet is generated in the first airflowchannel 13, a flow velocity of the air flow in the second airflowchannel 151 and the capillary liquid absorbing structure 152 isrelatively high, and correspondingly the air pressure is relatively low.Increase in the pressure difference between the second airflow channel151 and the vaporization cavity 132, that is, increase in a force thatdrives the accumulated liquid in the vaporization cavity 132 to enterthe second airflow channel 151 is facilitated, and reduction in theaccumulated liquid in the first airflow channel 13, especially reductionin the accumulated liquid at the bottom of the vaporization cavity 132is further facilitated, thereby alleviating the liquid leakage of thevaporizer 1 and improving the user experience.

In addition, the second airflow channel 151 is spaced apart from thefirst airflow channel 13. Specifically, the second airflow channel 151is spaced apart from the air outlet channel 131 and the vaporizationcavity 132, and the second airflow channel 151 is in communication withthe air outlet channel 131 and the vaporization cavity 132 through thefirst intersection 1511 and the second intersection 1512. Spacing apartis helpful to ensure the pressure difference between the second airflowchannel 151 and each of the air outlet channel 131 and the vaporizationcavity 132, to ensure that there is a sufficient pressure difference todrive the accumulated liquid in the vaporization cavity 132 to enter thesecond airflow channel 151, and to further ensure the formation of theforegoing complete airflow path.

Optionally, a partition 16 may be arranged between the second airflowchannel 151 and the first airflow channel 13, as shown in FIG. 1 , sothat the second airflow channel 151 is spaced apart from the firstairflow channel 13, which is not limited herein.

It should be noted that, the vaporizer 1 may further include aleak-proof cavity 15, the second airflow channel 151 and the capillaryliquid absorbing structure 152 are arranged in the leak-proof cavity 15,the leak-proof cavity 15 is spaced apart from the first airflow channel13, and the leak-proof cavity 15 intersects with and is in communicationwith the first airflow channel 13 through the first intersection 1511and the second intersection 1512 separately.

Certainly, in other embodiments of this application, the second airflowchannel 151 and the capillary liquid absorbing structure 152 mayalternatively be designed as being integrally formed in the vaporizer 1,which is described below, instead of additionally designing a leak-proofcavity 15 in the vaporizer 1 and then arranging the second airflowchannel 151 and the capillary liquid absorbing structure 152 in theleak-proof cavity 15, as described above.

In summary, two ends of the second airflow channel of the vaporizerprovided in this application separately intersect with the first airflowchannel to form a first intersection and a second intersection, wherethe first intersection is located between the first air outlet and thevaporization assembly, and the second intersection is located betweenthe first air inlet and the vaporization assembly. That is, the firstintersection is close to the first air outlet relative to the secondintersection. In this way, when an inhaling action occurs at the firstair outlet, an air flow from the first air inlet to the first air outletis generated in the first airflow channel, air pressure of the firstairflow channel at the first intersection is less than air pressure ofthe second airflow channel at the first intersection, and air pressureof the first airflow channel at the second intersection is greater thanair pressure of the second airflow channel at the second intersection.Therefore, a pressure difference between the first airflow channel andthe second airflow channel at the second intersection drives accumulatedliquid in the first airflow channel that is close to the secondintersection to enter the second airflow channel through the secondintersection and be absorbed by the capillary liquid absorbing structureto reduce the accumulated liquid in the first airflow channel,especially the accumulated liquid at the bottom of the vaporizationcavity. Therefore, alleviation of the liquid leakage of the vaporizerand the electronic vaporization device is facilitated, thereby improvingthe user experience and reducing the risk of damage to a main unit ofthe electronic vaporization device caused by the permeation of anaerosol substrate into the main unit.

A second communicationgroove 186 is provided on a portion of the dike 184 corresponding to thesecond intersection 1512, so that the first airflow channel 13intersects with the second airflow channel 151 to form the secondintersection 1512. The second communication groove 186 may also be agroove body similar to a capillary groove, which also absorbs theaccumulated liquid in the first airflow channel 13 by the capillaryforce.

Further, the plurality of capillary grooves 1521 are spaced apart andare parallel to each other in an extension direction of the secondairflow channel 151. After the capillary grooves 1521 that arerelatively close to the second intersection 1512 are filled up with theaccumulated liquid, the capillary grooves 1521 that are relatively faraway from the second intersection 1512 continue to absorb theaccumulated liquid until a storage amount of the accumulated liquid inthe plurality of capillary grooves 1521 reaches saturation. In addition,after the storage amount of the accumulated liquid in the plurality ofcapillary grooves 1521 reaches saturation, the leak-proof component 18is optionally detached for cleaning, so as to be used again, or thevaporizer 1 is optionally replaced with a new one, which is not limitedherein.

Certainly, in other embodiments of this application, the portion of theleak-proof component 18 where the second airflow channel 151 and thecapillary liquid absorbing structure 152 are located and the originalleak-proof component 18 may alternatively be an integral structure andcannot be disassembled or assembled, which is not limited herein.

Reference is made to FIG. 5 and FIG. 6 . FIG. 5 shows a situation ofaccumulated liquid in the first airflow channel 31 when the quantity ofinhaling of the user reaches 60, 90 and 120 according to a conventionalvaporizer 3. FIG. 6 shows a situation of accumulated liquid in the firstairflow channel 13 when the quantity of inhaling of the user reaches 60,90 and 120 according to the vaporizer 1 of this embodiment. In addition,FIG. 6 further shows a situation in which the capillary liquid absorbingstructure 152 absorbs the accumulated liquid when the quantity ofinhaling of the user reaches 60, 90 and 120 according to the vaporizer 1of this embodiment. It can be seen that the accumulated liquid in thefirst airflow channel 13 of the vaporizer 1 of this embodiment issignificantly reduced.

In summary, in the vaporizer provided in this application, a portion ofthe first airflow channel that is in communication with the firstintersection is close to the first air outlet relative to a portion ofthe first airflow channel that is in communication with the secondintersection in an extension direction of the first airflow channel. Inthis way, when the user inhales, an air flow from the first air inlet tothe first air outlet is generated in the first airflow channel, and airpressure of a portion of the first airflow channel that is incommunication with the second intersection is greater than air pressureat the second intersection of the second airflow channel. That is, thereis a pressure difference between two sides of the second intersection,and the pressure difference between the two sides of the secondintersection drives the accumulated liquid in the first airflow channelto flow into the second airflow channel through the second intersectionand be absorbed by the capillary liquid absorbing structure, to reducethe accumulated liquid in the first airflow channel, especially toreduce the accumulated liquid at the bottom of the vaporization cavity.Therefore, alleviation of the liquid leakage of the vaporizer isfacilitated and the user experience is improved.
